## 在 `q` 參數的型別中使用 `Annotated` { #use-annotated-in-the-type-for-the-q-parameter }

還記得先前在 [Python 型別介紹](../python-types.md#type-hints-with-metadata-annotations) 提到可以用 `Annotated` 為參數加入中繼資料嗎？

現在就用在 FastAPI 上吧。🚀

我們原本的型別註記是：

```Python
q: str | None = None
```

接著把它用 `Annotated` 包起來，變成：

```Python

 *  Fix: Don't infinite loop when a received web socket message has self-terminating compressed
    data.

 *  Fix: Don't fail the call when the response code is ‘HTTP 102 Processing’ or ‘HTTP 103 Early
    Hints’.

 *  Fix: Honor interceptors' changes to connect and read timeouts.

 *  Fix: Recover gracefully when a cached response is corrupted on disk.

 *  Fix: Don't leak file handles when a cache disk write fails.

- Kube-scheduler implemented scheduling hints for the `NodeAffinity` plugin. The scheduling hints allowed the scheduler to only retry scheduling a Pod that had been previously rejected by the `NodeAffinity` plugin if a new Node or a Node update matched the Pod's node affinity.

Puedes obtener el `root_path` actual utilizado por tu aplicación para cada request, es parte del diccionario `scope` (que es parte de la especificación ASGI).

Aquí lo estamos incluyendo en el mensaje solo con fines de demostración.

FastAPI é um framework web moderno e rápido (alta performance) para construção de APIs com Python, baseado nos type hints padrões do Python.

Os recursos chave são:

* **Rápido**: alta performance, equivalente a **NodeJS** e **Go** (graças ao Starlette e Pydantic). [Um dos frameworks Python mais rápidos disponíveis](#performance).
